To all whom it may concern;

Be it known that I, JOSEPH W; BAKER, a& citizen of the United States, residing at Corry, in the county of Erie and State of Pennsyl-- Vania, have invented certain new and useful Improvements in Washing-Machines; and I' do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specilication.

My invention consists in the improvements in washing-machines hereinafter set forth and I explained, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my im proved washing-machine with a wringer attached thereto. Fig. 2 is a cross-section of my machine on the line so a: in Fig. 1, showing the flexible removable wash-board raised up from the bottom, Fig. 3 is a cross-section of my machine with the wringer attached on the line a: a: in Fig. 1, with the roller mechanism removed. Fig. 4: shows a section of my improved flexible removable Wash-board.

Like letters refer to like parts in all the figures.

In the construction of my invention shown in the drawings, A is a tub, the bottom A of which is circular, made of sheet metal in the shape of ahalf-ellipse, as and for the purpose hereinafter set forth, secured to the ends B, so

0 O are the upright posts of the frame, each provided with feet 0 c, and secured together at their upper ends by cross-bars D D and at their lower ends by means of a cross-bar E, so as to form a firm and substantial frame.

To the central part of the upper edges 1) b of the ends B B of the tubA, I secure journals dd, which project outward into bearings in the upright posts 0 C, so that the tub A will oscillate freely thereon and may be readily oscillated by means of the handles 6 e thereon.

In the bottom of the tub A, I place a flexible removable wash-board F, made of fluted lags secured together by a strip of flexible material G, nailed across their ends on the back side thereof, and I removably secure this board in place in the tub A by means of stops. 9 hfsecured to the inside of the tub-bottom A, one of these stops 9 being permanently secured'in place, and the other h hinged to a strip H, secured to the inside of the tub-bottom, so that by raising the stop h the end of the flexible board can be raised, as illustrated in Fig. 2, and withdrawn from the tub.

Across the top of each side of the tub A, I secure strips of board I, which project over the inside of the tub sufficiently to prevent the water from splashing over the side of the tub When it is being oscillated.

To the cross-barsD D of the frameI secure tongued or grooved guides J J, which project downwardly therefrom into the tub A, near the ends B B thereof, within which guides are placed vertically-sliding bearings L L, moving independently of each other, in the lower ends of which the journals of the compressionroller M are mounted. These sliding bearings L L are normally'forced downward by means of the spiral springs 10 70, secured to the upper ends of the sliding bearings L L and to the upright posts C C of the frame by means of hooks i 2', so as to firmly press the roller M down upon the fluted board F in the semi-elliptical-shaped tub-bottom A, or upon clothing placed thereon, the bearings L L of the roller M and the springs 10 k thereon allowing the ends of the rollers M great freedom of movement to rise or fall independently of each other, so as to pass over bunches of clothes, as required; and on the tub A being oscillated the roller M travels to and fro over the elliptical-shaped wash-board F,with the pressure of the springs 70 7c gradually decreasing as the roller travels from the center toward the ends of the wash-board and increasing as it travels from the ends toward its center, this feature being accomplished by the half-elliptical shape of the tub-bottom A, thus bringing the greatest pressure of the roller upon the central portion of the tub, where the greatest amount of work is to be done, and reducing it toward the ends of the board, thereby equalizing and greatly diminishing the power required to operate the machine.

hen it is desired to raise the roller M off of the board F, as shown in Fig. 2, the sliding bearings L L are raised up and small pins m m placed in holes therein, which retain the roller M in the position shown in Fig. 2.

The roller M, Imake with a longitudinallyfluted periphery, and bore therein a large number of radial holes N, which do not passentirely through the roller, so that as it is ro tat'ed the airin the holes N is discharged under the Water used in the tub, so as to better agitate it and assist the process of washing thereby.

To the upper part D D of my machineframe I secure a wringer O, of ordinary construction, and to theouter edgeof the apron P thereof I hinge an extension Q, by means of small hooks n, so that it can he removed or folded back against thewringer 0 when desired, the object and use of this extension Q being to convey the clothes over the rear edge of the tubA When the wringer O is'being used.

I I am aware of the patent to Christopher, No.

177,374, dated May 16, 1876, and therefore I do not claim,broadly, an oscillating tub having a circular fluted Wash-board and a compression-roller operating thereon; but

hat I do claim, and desire to secure by Letters Patent of the United States, is

The combination, in a Washing-machine, of an oscillating tub A, having a semi-ellipticalshaped bottom A and a fluted Wash-board F therein, With a fluted compression-roller M, mounted in vertically-moving bearings L L, having compression-springs la 76 secured to said bearings and to the frame, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOSEPH V. BAKER.
